Second world record of Glomus trufemii (Glomeromycota: Fungi), an arbuscular mycorrhizal fungus from a Mexican savanna

In Mexico, studies of diversity of arbuscular mycorrhizal fungi (AMF) are still scarce. Here we report the second record in the world, and the first record in Mexico of Glomus trufemii (Glomeraceae) from a tropical humid savanna. These results provide an incentive to increase inventories of AMF in savannas, as well as to preserve this endangered ecosystem.
